Streaming / Embedded video

Just Burny

Whats the best add-in/ plugin for watching embedded and/or streaming videos off the net? Either for firefox or opera etc. I have an eeepc and I'm finding that with some videos it's very grainy/rough and now and again it's running choppy with sound and video. I don't know whether it's the browser I used (opera at the time). I might just stick with firefox 3 for it as i've both installed on here.

EDIT: a little more info: where I appear to be running into problems on both browsers (opera/firefox) is on the demo. It's very choppy sound/ audio. When I watch a video say on nfl,.com, it seems to run fine. same with youtube. Maybe a little slow but usually fine. I know it could be three different types of players used by each site. I'm just wondering if someone with more info about it can help me.
Any full episodes on suck fucking balls for me. All the other major network sites work fine but NBC sucks the donkey's ass.
